Manage a k3s Kubernetes cluster on Raspberry Pi.

Move to the ansible_setup directory and use Ansible to install on the Raspberry Pi(s) everything is needed. Download the kubeconfig file from the Raspberry Pi and install it locally (in ~/.kube/config), replace the server value with the FQDN of the Raspberry Pi (instead of localhost).

Once kubectl is installed on the workstation, verify that works with the kubeconfig file downloaded, e.g. kubectl cluster-info.

I use the excellent Bitwarden as my personal cloud-based password storage, once the CLI is installed on the workstation, it can be used to synchronize the secrets to the Kubernetes cluster on the Raspberry Pi.

Grafana credentials:

kubectl --namespace metrics create secret generic grafana-admin-credentials --from-literal=username=$(bw get username grafana.raspi.hal) --from-literal=password=$(bw get password grafana.raspi.hal)

Deploy FluxCD: execute ./flux/bootstrap_flux.sh. FluxCD will take care of applying all the manifests defined in kubernetes directly from this GitHub repository.

Discord webhook for notifications:

kubectl --namespace flux-system create secret generic discord-url --from-literal=address=$(bw get password discord-webhook)
